Customer Reviews (4.6 / 5 · 5 reviews)

Jacob O. ★★★★★

I needed a bulk set for a small project, and the 1500 count is more than enough for future repairs. These #1 lock washers fit the bolts perfectly and feel tough enough to handle vibration without stripping.

Zoe ★★★★★

The 410 stainless steel feels sturdy and corrosion-resistant, perfect for automotive work. Opened the 1500-count package and found every washer uniform in thickness and tooth depth. These lock washers bite well into the fastener head, holding tight under heavy vibration.

Ella J. ★★★★★

Was pleasantly surprised by the quality of these #1 lock washers — the 410 stainless steel feels solid and corrosion-resistant. They're holding up perfectly on a small engine mounting bracket I've been working on, no loosening after hours of vibration. A solid buy for the price.
